UMBRELLA.

Application filed. August 22, 1924. Seria1No. 733,635. I

To (ZZZ whom it may concern:

Be it known that I, ABRAHAM VVILLIAM lVoLrsoN, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved Umbrella, of which the following is a full, clear, and exact description.

This invention relates to umbrellas, and more particularly to umbrellas,-parasols and similar devices, and I would have it understood thathereinafter while I shall refer to the device as an umbrella I use this term in its broadest sense to cover any analogous device.

An object of the invention is to improve upon the construction disclosed in Patent No. 892,473, granted July 7, 1908, to H. G..

Walters, and the invention is directed particularly to an improved construction of rib fulcrum and collar with improved coupling means whereby the rib coupling is prevented from turning movement when the umbrella is open, and the rib fulcrums are capable of movement away from the collar when undue wind pressure is had with a tendency to turn the umbrella wrong side out. The parts of this invention are, therefore, substantially the same as those of the patent above referred to except that a difference in the construction of the rib fulcrum and collar constitutes the invention per se.

lVith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a view in section, partly in elevation, showing the umbrella in open position and provided with my improvements;

Figure 2 is an enlarged view showing my improved rib fulcrum and collar in longitudinal section on the rod;

Figure 3 is a view in transverse section on the line 33 of Figure 2;

Figure at is a perspective view of my improved rib fulcrum.

1 represents the umbrella rod to which a collar 2 is secured by a pair of rivets 3 projecting at right angles to each other and through the rod and collar, the lower portion of the collar being flared -01- enlarged so as to receive my improved'rib fulcrum 4.

This rib fulcrum 4 is made with recesses" 5 adapted to receive the rivets 3, and it. will be noted that the outer *ends of the recesses have their walls slightly rounded' so' as to guide them into operative engagement with the rivets or pins, and that'the depth of two opposed recesses is less than'the depth of the other pairof recesses so that when the fulcrum is in position inthe eol-' lar the rivets or'pins are-located'in the ends or base portions of the recesses. I By reason of'this construction the rib fulcrum is properly guided into interlocking engagement with the rivets or pins of the collar and a strong and durable engagement is had. This part of the umbrella is necessarily subjected to considerable wearas the umbrella is frequently opened andclosed and there is some movement always when the wind is high so'that it is desirable I that this engagement be such as. to prevent I undue wear. Therefore, by providing four I recesses w th a pa r of pins or rivets a plu-' rahty of contact points 1s had which insures a proper coupling and prevents undue wear,

which would be the case with a reduced number of recesses and contact points with the pins or rivets. I

While the invention is not limited, of course, to the particular arrangement of parts, I preferably employ the arrangement set forth in the patent above referred to in which the ribs 6 are connected to the ful-Q crums A: and the stays 7 connect the ribs with the runner 8 on rodl. The umbrella cover 9 is connected at its outer end to the ribs 6 and at its inner end is secured under a cap 10 in any approved manner.

By reason of the construction. above described, the fulcrums 4; can move away from the collar 2, as indicated by dot and deer I and alterations as fairly fall within the spirit and scope of the appended claims.

I claimz 1. In an umbrella, the combination With a rod, a collar on the rod, a cover secured over the collar, a rib fulcrum mounted to move on the rod, ribs connected to the fulcrum and to the cover, a runner on the rod, stays connecting the ribs and the runner, said ful crums-adapted to move into-the collar, a pair of rivets or pins projected through the collar and through the rod, and said fu-lcrum having recesses therein receiving the pins or rivets.

2. In an umbrella, the combination with arod, a collar on the rod, a cover securedover the collar, a rib 'fulcrum mounted to move on the rod, ribs connected to the fulcrum and to the cover, a runner on the rod,stays eonmeeting the ribs and the runner, said fulchum; adapted to move into the collar, and a pair of-rivets or pins projectedthrough ei-sense the collar and through the rod and said fulcrum having recesses therein receiving the pins or rivets, said recesses in the collar being of a length to seat the rivets or pins in the bottoms or bases of said recess'eswhen the ribcoupling and collar are together.

3. In an umbrella, the combination with a having recesses therein receiving the pins or r1vets,v sa2 d. recesses m the 'col-lar being of a length to seat the rivets or pins in the bottoms or bases of sa-idrecesses when the rib'coupling and collar are together, said recesses havin flared entrance ends.
